Not the best strategy and doesn't generate much in the way of returns or income quite frankly. That said, I'm not an option trader and general only use options as a hedging strategy, primarily for my high yield fixed income book.
If you are dead set on buying XOM and feel comfortable owning the stock and that it's not going to drop, a much better strategy would be to purchase XOM and short the May 70/62.5 strangle for ~$0.52. And then repeat this strategy every month (adjusting strike prices accordingly).
Assuming a relatively stable stock price and stable volatility (which if you're willing to purchase the stock outright and short a call for income, you should believe), by Jan '11, you'd create ~$450 in short sale proceeds (assuming stable vol) and you'd receive $132 in dividend proceeds.
$582 of income versus $222 in your strategy. Conversely, if we assume that XOM can't recoup the dividend payouts through price appreciation, then the spread is even greater, $450 versus $90.
One thing to keep in mind, you're short volatility on this trade, effectively betting that XOM will stay within the range of the options you're short. XOM rises, you don't participate, XOM falls and you participate x2. It's a good strategy in a low vol stock (or one that you believe will exhibit less vol than the intrinsic vol inferred by the price of the options you're shorting), not such a good one for a high volatility stock unless it's one you are willing to double down on if the price decreases.
I would suggest you do a lot of studying up on options strategies. There are ways to make money, but they requier a lot of thought and understanding of how options work and the pricing methodology behind them. Back in the day I read Dynamic Hedging (which is a graet book), but I believe there are quite a few books that have surpassed it as the Options trader's bible by now.
